"Summicron" is the Leica f/2-class lens in 35, 50 and 90mm with highest
reputation for performance and all-purpose usage among Leica-owners.
The name Summicron has some legendary sound. This lens by some
was sometimes called the "Japanese
For some reasons it could be
seen as regression, because Canon already made a 1.8/35 in 1956
(which was together with the Nikkor the fastest at this time, and
an excellent lens) and, 1958, an 8-elements 1.5/35 which again was
the fastest wide-angle of that time. Oppinions about quality of the
latter are divided, some say "speed" was seen more important as
and sharpness at design, like it was with the 0.95/50...
April 1962 the 2.0/35 came out and replaced both in production - with 7
elements/ 4 groups a derivation if the
1.8/35, but sharper and more contrasty in the center. And from the
formula, very similar to the - later! - 7 elements Summicron design...

Furthermore black, small, and lightweight - just a handfull glass and
alloy. Finally without "infinity lock". Looks like a Mini-SLR-lens, but
disappears in a trouser pocket. The unimpressive outline doesn't hide
the excellent working. Not cheap. Rare and sought-after. Whoever owns
one don't give it away untill he gets something better. This is - 40
after debut - available but costs much more.
